I am preparing raster surfaces to do a multi criteria evaluation in ArcGIS 10. I need to create a raster surface that contains distance values for each cell from the electricity grid. However, my data for the grid is contained in two shapefiles - a point file (e.g. poles, pylons) and a line file (electricity lines). I can't merge the vector files because they are different types.
Is there a way of creating a raster surface where each cell value is the distance from any part of the grid; e.g. distance from a point or a line?
